This late in the year, I always question if the juvenile I'm watching near a nest site is from the nest or a migrating juvenile whose just passing through. This happens frequently in Central Park, but I saw it for the first time in Tompkins Square Park yesterday. The juvenile I saw was definitely not the surviving fledgling. It had very different tail feathers and different chest markings.

Regardless of who this hawk is, it was great to watch. It ended up having a fun interaction with two squirrels.
